A coacervate-based mixed-conducting binder for high-power, high-energy batteries

This data set accompanies the article \"A Coacervate-Based Mixed-Conducting Binder for High-Power, High-Energy Batteries\" published in ACS Energy Letters in 2023 (https://doi.org/10.1021/acsenergylett.3c00829). The article demonstrates a strategy for imparting electronic and ionic conductivity to battery binders, while also maintain facile processing capability. Polymer binders add crucial structural integrity to lithium ion battery composite cathodes, but industry standard binders, such as polyvinylidene fluoride (PVDF), are insulating to ions and electrons, detrimentally adding resistance to the overall system. In this work, we use electrostatics to stabilize a blend of a charged conjugated polymer with an oppositely charged polyelectrolyte, providing a processable, stable binder with high ionic and electronic conduction. Using LiFePO4 cathodes as a model system, we show significant improvement in rate capability and stability, with the conducting binder enabling a 39% utilization at ..., , Data is in non-proprietary csv and txt formats
